The Administration of Spain Under Charles V, Spain's New Charlemagne (open access)

The Administration of Spain Under Charles V, Spain's New Charlemagne

Charles I, King of Spain, or Charles V, Holy Roman Emperor, was the most powerful ruler in Europe since Charlemagne. With a Germanic background, and speaking French, Charles became King of Spain in 1516. Yet secondary sources and available sixteenth century Spanish sources such as Spanish Royal Council records, local records of Castro Urdiales in Castile, and Charles's correspondence show that he continued the policies of his predecessors in Spain, Ferdinand of Aragon and Isabella of Castile. He strove to strengthen his power and unify Spain and his empire using Castilian strength, a Castilian model of government, Roman law, religion, his strong personality, and a loyal and talented bureaucracy. Charles desired to be another Charlemagne, but with his base of power in Spain.

Amon Carter: The Founder of Modern Fort Worth, 1930-1955 (open access)

Amon Carter: The Founder of Modern Fort Worth, 1930-1955

From 1930 to 1955, Amon Carter, publisher of the Fort Worth Star-Telegram, exerted his power to create modern Fort Worth. Carter used his stature as the publisher of the city's major newspaper to build a modern city out of this livestock center. Between 1930 and 1955, Carter lobbied successfully for New Deal funds for Fort Worth, persuaded Consolidated Aircraft to build an airplane plant in the city, and convinced Burlington Railways to stay in the city. He also labored unsuccessfully to have the Trinity River Canal built and to secure a General Motors plant for Fort Worth. These efforts demonstrate that Carter was indeed the founder of modern Fort Worth.

Challenges Encountered During Law Enforcement Investigations of Terrorist Use of Information Technology.

Access: Use of this item is restricted to the UNT Community
The late 20th and early 21st centuries have seen a phenomenal growth in society's use of information technology. Criminals, including terrorists and terrorist organizations, have also adopted information technologies. Information technologies are used to enhance the efficiency, productivity, and effectiveness of terrorist activities and offenses. Investigating terrorist use of information technologies creates a number of challenges for law enforcement officials. While some of the challenges are encountered during conventional criminal investigations, terrorist investigations also present unique challenges. Through content and typological analysis, this study examined open source information to identify, categorize and propose a model of these challenges. Four primary categories were identified: technology, methodology, legal, and administration and human resources challenges.

Connecting Ireland and America: Early English Colonial Theory 1560-1620 (open access)

Connecting Ireland and America: Early English Colonial Theory 1560-1620

This work demonstrates the connections that exist in rhetoric and planning between the Irish plantation projects in the Ards, Munster , Ulster and the Jamestown colony in Virginia . The planners of these projects focused on the creation of internal stability rather than the mission to 'civilize' the natives. The continuity between these projects is examined on several points: the rhetoric the English used to describe the native peoples and the lands to be colonized, who initiated each project, funding and financial terms, the manner of establishing title, the manner of granting the lands to settlers, and the status the natives were expected to hold in the plantation. Comparison of these points highlights the early English colonial idea and the variance between rhetoric and planning.

Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing (open access)

Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing

The Rocker b Ranch on the southern Rolling Plains has one of the last sizeable populations of pronghorn (Antilocapra americana) in Texas. To investigate habitat utilization on the ranch, pronghorn were fitted with GPS/VHF collars and were released into pastures surrounded by a variety of fences to determine how fence types affected habitat selection. Habitat parameters chosen for analysis were vegetation, elevation, slope, aspect, and distances to water, roads, and oil wells. Results showed that pronghorn on the ranch crossed modified fencing significantly less than other types of fencing. Pronghorn selected for all habitat parameters to various degrees, with the most important being vegetation type. Habitat selection could be attributed to correspondence of vegetation type with other parameters or spatial arrangements of physical features of the landscape. Seasonal differences in habitat utilization were evident, and animals tended to move shorter distances at night than they did during daylight hours.

Documentary Film: I Named Her Angel

Access: Use of this item is restricted to the UNT Community
Recent political developments in the world show us that different cultures need to know and understand each other better. Even though technological developments like the Internet, satellites, cable television and conglomeration of big media entities have made mass communication more effective and faster, we cannot easily say that these developments help to bring world cultures together. As a result, mass audiences are not very much able to see what few productions do speak to these issues in a constructive manner. The main aim of this documentary film project is to serve as a small step towards helping different cultures to understand each other better. This documentary film conveys the basics of Mevlevism by following the formal gatherings of a Mevlevi den in Istanbul, Turkey. A den or tekke is a place where Islamic people gather and perform their religious activities. During these gatherings they do the sema, they pray, they listen to music, and they discuss spiritual matters. Sema is the entire ritual they perform as part of their ceremonies including listening to music, singing and chanting to attain a state of religious emotion and ecstasy or vecd. The documentary film is structured around a twelve year old girl, Elif, …

Many Christian writers point to God through their fiction without openly evangelizing. The images their words evoke lift their secular and religious readers' heads, for God is reflected in their use of language, the emotions they describe, and the actions of their characters. The preface and short stories in this collection aim to show that God's presence can be felt even when people are suffering due to human decisions and mistakes. He is with His creations in the midst of their pain to impart hope when they need it most.

The Effects of Bilingual Education on Reading Test Scores: Can Dual-immersion Support Literacy for All Students? (open access)

The Effects of Bilingual Education on Reading Test Scores: Can Dual-immersion Support Literacy for All Students?

Dual-immersion is a bilingual education method offered that places English as a first language (EFL) and English language learner (ELL) students in the same classroom to learn two languages at the same time. This study examines whether second language acquisition through dual-immersion supports literacy for both ELL and EFLS children over time. Students' scores on standardized tests (ITBS, TAKS, Logramos, Stanford 9, and Aprenda) were studied to assess the impact, if any, of dual-immersion instruction vs. regular/bilingual education on reading development. Scores from 2000 through 2004 were gathered and analyzed for students enrolled in a dual-immersion class which started in kindergarten in 2000. These scores were compared to scores of students enrolled in regular and bilingual education classrooms for the same amount of time at the same school to examine whether there was an effect for students in the dual-immersion class. It was found that no significant difference existed between the groups. All groups were performing at a passing level on the standardized tests. The dual-immersion class was performing as well as the regular education class on standardized tests in both English and Spanish.

Access: Use of this item is restricted to the UNT Community
The purposes of this study were to examine the (a) attentional focus strategies used by high school distance runners, (b) changes in attentional focus across four laps in three 1.6 km runs, and (c) effects of a pre-performance intervention using motivational and instructional self talk on the attentional focus strategies used by and performance of high school distance runners. Participants (N = 42) completed a background and demographic questionnaire, the Cross Country Attentional Focus Inventory (CCAFI), a motivational and instructional statement survey, and the Self-Motivation Inventory. A series of oneway ANOVAs revealed significant differences in the types of attentional strategies used by each group, as well as fluctuations in use of strategies. The experimental group associated more during the each of the 1.6 km trials, whereas the control group dissociated more throughout each trial. A significant group by week interaction was found, with the experimental group maintaining their performance and the control group slowing from week one to week three.

An Empirical Evaluation of Communication and Coordination Effectiveness in Autonomous Reactive Multiagent Systems (open access)

An Empirical Evaluation of Communication and Coordination Effectiveness in Autonomous Reactive Multiagent Systems

This thesis describes experiments designed to measure the effect of collaborative communication on task performance of a multiagent system. A discrete event simulation was developed to model a multi-agent system completing a task to find and collect food resources, with the ability to substitute various communication and coordination methods. Experiments were conducted to find the effects of the various communication methods on completion of the task to find and harvest the food resources. Results show that communication decreases the time required to complete the task. However, all communication methods do not fare equally well. In particular, results indicate that the communication model of the bee is a particularly effective method of agent communication and collaboration. Furthermore, results indicate that direct communication with additional information content provides better completion results. Cost-benefit models show some conflicting information, indicating that the increased performance may not offset the additional cost of achieving that performance.

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Access: Use of this item is restricted to the UNT Community
Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results indicate that overall methodological rigor is not a significant predictor of organizational change outcomes; however, several individual rigor criteria exhibit predictive power. Implementation quality is a significant predictor of organizational outcomes, but in a negative direction.

Exploring job related stress and job satisfaction in a modern law enforcement communications division. (open access)

Exploring job related stress and job satisfaction in a modern law enforcement communications division.

One of the most neglected areas of criminological and social science research is the police communications or dispatch center. While research projects dealing with stress and job satisfaction are found in abundance for other occupations, studies specific to the police dispatcher are uncommon. The role of the dispatcher has changed significantly in the last few decades. Improvements in technology and changes in public expectations of emergency services have forever altered the communications professional. Dispatchers work in an environment reliant on information. There is tremendous pressure to process the information coming into a communications center quickly and correctly. A mistake could prove fatal. Work pressures, burnout, high employee turnover, low pay, and a lack of respect from police coworkers can easily result in negative emotional and psychological consequences for the dispatcher. An effective manager could reduce the feelings of stress and low job satisfaction this environment can facilitate. The current study utilizes survey data from a sample of police dispatchers and their managers in the Dallas/Fort Worth, Texas area. The purpose of the survey is to identify the level of stress and job satisfaction reported by the dispatchers and their managers. The effects of differing types of stress will be investigated. …

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products (open access)

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products

A number of lifestyle merchandising and advertising strategies are being used in the home furnishings industry. However, there is limited research regarding the effectiveness of these strategies. The purpose of this study was to explore consumers' attitudes toward the lifestyle concept. Analyses of several consumer behavior variables and descriptors offered noteworthy findings for the home furnishings industry. This study found that although lifestyle orientation is a valuable tool for delineating consumer markets, these segmentations were not significant determinates of consumers' preference for elements of the lifestyle construct. Retailers and manufacturers are not simply creating home furnishing collections that target the needs of specific psychographic segment, but rather creating lifestyles being aspired to obtain. Although respondents scored the attitude variables neutral, the current market environment offers many examples of successfully home furnishing implementations of the lifestyle concept. These success stories coupled with additional findings indicate consumers' positive response to lifestyle merchandising.

FP-tree Based Spatial Co-location Pattern Mining (open access)

FP-tree Based Spatial Co-location Pattern Mining

A co-location pattern is a set of spatial features frequently located together in space. A frequent pattern is a set of items that frequently appears in a transaction database. Since its introduction, the paradigm of frequent pattern mining has undergone a shift from candidate generation-and-test based approaches to projection based approaches. Co-location patterns resemble frequent patterns in many aspects. However, the lack of transaction concept, which is crucial in frequent pattern mining, makes the similar shift of paradigm in co-location pattern mining very difficult. This thesis investigates a projection based co-location pattern mining paradigm. In particular, a FP-tree based co-location mining framework and an algorithm called FP-CM, for FP-tree based co-location miner, are proposed. It is proved that FP-CM is complete, correct, and only requires a small constant number of database scans. The experimental results show that FP-CM outperforms candidate generation-and-test based co-location miner by an order of magnitude.

Functional and Categorical Analysis of Waveshapes Recorded on Microelectrode Arrays (open access)

Functional and Categorical Analysis of Waveshapes Recorded on Microelectrode Arrays

Dissociated neuronal cell cultures grown on substrate integrated microelectrode arrays (MEAs) generate spontaneous activity that can be recorded for up to several weeks. The signature wave shapes from extracellular recording of neuronal activity display a great variety of shapes with triphasic signals predominating. I characterized extracellular recordings from over 600 neuronal signals. I have preformed a categorical study by dividing wave shapes into two major classes: (type 1) signals in which the large positive peak follows the negative spike, and (type 2) signals in which the large positive peak precedes the negative spike. The former are hypothesized to be active signal propagation that can occur in the axon and possibly in soma or dendrites. The latter are hypothesized to be passive which is generally secluded to soma or dendrites. In order to verify these hypotheses, I pharmacologically targeted ion channels with tetrodotoxin (TTX), tetraethylammonium (TEA), 4-aminopyridine (4-AP), and monensin.

N-Heterocyclic Carbenes of the Late Transition Metals: A Computational and Structural Database Study (open access)

N-Heterocyclic Carbenes of the Late Transition Metals: A Computational and Structural Database Study

A computational chemistry analysis combined with a crystallographic database study of the bonding in late transition metal N-heterocyclic carbene (NHC) complexes is reported. The results illustrate a metal-carbon bond for these complexes, approximately 4% shorter than that of a M-C single bond found in metal alkyl complexes. As a consequence of this result, two hypotheses are investigated. The first hypothesis explores the possibility of multiple-bond character in the metal-carbon linkage of the NHC complex, and the second, considers the change in the hybridization of the carbenoid carbon to incorporate more p character. The latter hypothesis is supported by the results. Analysis of these complexes using the natural bond orbital method evinces NHC ligands possessing trans influence.

Institutions and Drug Markets (open access)

Institutions and Drug Markets

This thesis examines how drug policy and enforcement affect drug manufacturers. The approach taken is a comparative institutional analysis of cannabis and methamphetamine production. I focus on the effects of prohibition, privacy, and clandestine markets on producer behavior for these two drugs and the unintended consequences that result. I demonstrate that cannabis and methamphetamine producers both face substantial transaction costs and that producers alter their behavior to manage these transaction costs. I conclude that cannabis producers can adopt indoor, small-scale operations to hide their activity, which are capable of yielding continuous, high-potency crops. Methamphetamine producers also adopt small-scale, decentralized strategies, but commodity control increases their exposure and leads to greater overall transaction costs during the manufacturing process.

Interfacial Study of Copper Electrodeposition with the Electrochemical Quartz Crystal Microbalance (EQCM) (open access)

Interfacial Study of Copper Electrodeposition with the Electrochemical Quartz Crystal Microbalance (EQCM)

The electrochemical quartz crystal microbalance (EQCM) has been proven an effective mean of monitoring up to nano-scale mass changes related to electrode potential variations at its surface. The principles of operation are based on the converse piezoelectric response of quartz crystals to mass variations on the crystal surface. In this work, principles and operations of the EQCM and piezo-electrodes are discussed. A conductive oxide, ruthenium oxide (RuO2) is a promising material to be used as a diffusion barrier for metal interconnects. Characterization of copper underpotential deposition (UPD) on ruthenium and RuO2 electrodes by means of electrochemical methods and other spectroscopic methods is presented. Copper electrodeposition in platinum and ruthenium substrates is investigated at pH values higher than zero. In pH=5 solutions, the rise in local pH caused by the reduction of oxygen leads to the formation of a precipitate, characterized as posnjakite or basic copper sulfate by means of X-ray electron spectroscopy and X-ray diffraction. The mechanism of formation is studied by means of the EQCM, presenting this technique as a powerful in-situ sensing device.

A magnetorheological study of single-walled and multi-walled carbon nanotube dispersions in mineral oil and epoxy resin. (open access)

A magnetorheological study of single-walled and multi-walled carbon nanotube dispersions in mineral oil and epoxy resin.

Single wall carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) were dispersed in mineral oil and epoxy resin. The magnetorheological properties of these dispersions were studied using a parallel plate rheometer. Strain sweeps, frequency sweeps, magneto sweeps and steady shear tests were conducted in various magnetic fields. G', G", h* and ty increased with increasing magnetic field, which was partially attributed to the increasing degree of the alignment of nanotubes in a stronger magnetic field. The SWNT/mo dispersions exhibited more pronounced magnetic field dependence than SWNT/ep and MWNT/mo counterparts due to their much lower viscosity. The alignment of SWNTs in mineral oil increased with rising nanotube concentration up to 2.5vol% but were significantly restricted at 6.41vol% due to nanotube flocculation.

Meta-parenting, defined as parents thinking about their parenting, has been identified and is a new field of research. The purposes of this study were to add to the existing knowledge of meta-parenting and to compare the influences of gender, work status, and parenting experience on meta-parenting occurring in parents of infants and toddlers. Sixty parents participated either electronically or by completing a written survey and reported engaging from "sometimes" to "usually" in four domains of meta-parenting: anticipating, assessing, reflecting, and problem-solving. Gender, work status, and parenting experience did not significantly influence participants' meta-parenting scores. Parents were found to have a higher sense of satisfaction and overall sense of competence when they engaged in higher levels of meta-parenting.

Molecular and biochemical characterization of phospholipase D in cotton (Gossypium hirsutum L) seedlings.

Access: Use of this item is restricted to the UNT Community
N-Acylethanolamines (NAEs) are enriched in seed-derived tissues and are believed to be formed from the membrane phospholipid, N-acylphosphatidylethanolamine (NAPE) via the action of phospholipase D (PLD). In an effort to identify a functional NAPE-PLD in cotton seeds and seedlings, we have screened a cotton seedling cDNA (cotyledon mRNA from 48 h dark grown seedlings) library with a 1.2 kb tobacco partial cDNA fragment encoding the middle third of a putative PLDβ/γ (genbank accession, AF195614) isoform. Six plaques were isolated from the Uni-ZAP lambda library, excised as pBluescript SK(-) phagemids and subjected to nucleotide sequence analysis. Alignment of derived sequences with Arabidopsis PLD family members indicated that the cDNAs represent six different PLD gene products -three putative PLD β isoforms and three putative PLD δ isoforms. The PLD β isoforms, designated Ghpldβ1a, GHpldβ1b and a truncated Ghpldβ1b isoform. Both the full-length PLD β proteins contained characteristic HKxxxxD catalytic domains, a PC-binding domain, a PIP2-binding domain and a C2 domain. In addition both cotton PLD β isoforms had a N-terminal "SPQY" rich domain which appeared to be unique to these PLDs. The three PLD δ isoforms, designated Ghpldδ1a, Ghpldδ1b and Ghpldδ1b-2 encode full-length PLDδ proteins, and like the above PLDs, contained the …
